APPARATUS FOR TREATING SLAG.

' SPECIFICATION forming part of Letters Patent No. 628,399, dated J'u1y4, 1899.

Application filed September 22, 1897. Renewed June 7 1899. Serial No, 719,729. No model.)

' To all whom it may concern.-

Be it known that I, CHARLES DIEBOLD, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Treating Slag; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to apparatus for treating furnace-slag for the purpose of makingslag spout and spreader on an enlarged scale;

Fig. 4, a side elevation of one of the molds and part of the rim of the wheel; Fig. 5, a vertical section of one end of the mold; Fig. 6, an inverted plan of the mold; Fig. 7, afront end view of the cinder receptacle or spreader on an enlarged scale, and Fig. 7 an enlarged section and side elevation of the cooling-pipe.

Reference being had to the drawings and the letters thereon, A indicates a wheel or mold-carrier supported on an axle a, which is supported at each end in suitable pillow blocks or bearings (7 band the Wheel suspended in a pit B. are secured rims d d", connected by transverse bars (1 only one of which is shown in Fig. 2, and upon the periphery of the wheel are secured a series of curved molds C, which extend throughout the circumference of the wheel and are secured thereto by lugs e e, which straddle both the rims d d and are secured in position by rods or bolts e e which extend through each pair of lugs.

The sides f of the molds C are slightly inclined outward and the end 9 inclined inward and the end g inclined outward, the angle of the two ends of the molds being the same, so that the ends of the molds overlap each other on the wheel, and when they be- To the arms 0 c of the wheel come heated by the slag and expand the end g of one mold rides upon the end 9 of the adjaceut mold, the rising of that end of the mold being provided for by the rods or bolts 6 which are some distance from the rims d d and normally out of engagement with the under side of the rims, as shown in Figs. 1 and 4. The molds are. curved to conform to the curve of the rims d d, but are held out of engagement therewith by transverse ribs 7L between the lugs c and e to prevent heat-' ing and expanding the rims. On each side of the rib 71. of the lugs e rivets or bolts i are inserted through the rims d (l forthe purpose of holding the molds in proper position.

D indicates the slag or cinder spout, from which slag is discharged through end plate 7c, having opening Z into a receptacle or spreader E, arranged to discharge the slag into the molds C as the wheel bearing the molds revolves by power applied to the driving-pulley F from any suitable motor. The bottom of the spreader may becovered with refractory material m, such as fire-brick, and the sides at n and rear .end 0 are secured to the bottom; but the front 19, which forms the gate or valve to regulate the flow of slag into the molds, is separate from the bottom and sides, is raised by a lever q, attached to shaft 7', which is connected to the gate by arms 5 s, which engage studs or pins t on the ends of the gate.

The gate is prevented swinging outward by the pressure of the slag in the spreader by levers 21, having weights u on one end, and is secured to shaft or rod w, supported in brackets y, with the ends 2 of the levers bearing against the outer surface of the gate.

G G indicate pipes perforated, as shown at a; in Fig. 7 and arranged on each side of the wheel A to project streams of water against the under side of the bottom of the molds O to cool the slag in the molds.

The slag receptacle or spreader E is arranged to deliver slag to the molds -in a thin sheet as the wheel A revolves, and the thickness of the slabs formed in the molds is regulated by the speed of the wheeland the temperature at which the molds are kept by the cooling medium employed, the overflowing slag being prevented from getting between the molds by their overlapping ends.

H indicates a chute upon which slag runceives the chilled contents of the molds as they aredischarged by the Wheel in its revo-- lution and are raised out of the pit B by the conveyer.

Having thus fully described my invention,

' What I claim is 1. A revoluble Wheel mold-carrier having a series of molds secured to the periphery thereof at one of their ends, the other end of each mold being free to rise and slide on said periphery as the molds are expanded by heat, in combination with means for supplying liquid slag to the molds.

2. A revoluble Wheel mold-carrier, in combination with a series of molds provided with overlapping adjacent ends and secured to the periphery of said Wheel at one of their ends, the other end of each mold being free to rise and slide on said periphery as the molds are expanded by heat, and means for supplying Eliquid slag to the molds.

3. A revoluble Wheel mold-carrier, in combination with a series of molds provided with oppositely-inclined and overlapping ends of the same angle and secured to the periphery of the Wheel at one of their'ends, the other end of each mold being free to rise and slide on said periphery as the molds are expanded by heat, and means forsupplyingliquid slag to the molds- 4. A revoluble Wheel mold-carrier having peripheral rims, a series of molds provided with lugs at each end, the lugs at one end being rigidly secured to the rims and those at the opposite end movably engaging said rims to secure the molds and permit expansion thereof and having ends of the same angle of inclination overlapping each other at adjacent ends of the molds, in combination with means for supplying liquid slag to the molds.

5. A revoluble wheel mold-carrier having a series of molds secured to the periphery thereof, in combination with a device for supply-.

ing slag to the molds, a fixed chute arranged in position to receive the overflow from the molds and a conveyer arranged to receive the slag from the molds and the slag from the chute.

6. A revoluble wheel mold-carrier having a series of molds secured to the periphery thereof, in combination With a slag receptacle or spreader provided with a vertically-movable gate, arms or levers engaging the gate, and Weights for retaining the gate in its normal vertical position.

'7. Arcvoluble wheel mold-carrier having a series of molds secured to the peripherythereof at one of their ends, the ends of each mold being free to rise'and slide on said periphery as the molds are expanded by heat in combination With pipes arranged to direct streams of Water against the bottom of the molds, and means for supplying liquid slag to the molds.

8. A revoluble Wheel mold-carrier, in combination with a series ofmolds curved to conform to the periphery of the Wheel, provided with inclined and overlapping adjacent ends of the same angle of inclination and secured to the Wheel at one of their ends, the other end of each mold being free to rise and slide on said periphery as the molds are expanded by heat.

9. A revoluble Wheel mold-carrier, in combination With a series of molds, curved to conform to the periphery of the Wheel and provided with lugs on the bottoms thereof, arranged in pairs to connect the molds to the carrier and transverse ribs between the lugs.

In testimony whereof I affix my signature in. presence of two Witnesses.
